Is this used for backward compatibility with the OIDC servers?

Is this option used in the wild? As far as I understand the main use case is a 3rd party signing the request object that way entitling the client for something. I‘m asking since in my experience any kind of entitlement by a 3rd party is handled behind the scene using registries.
